Select the correct answer.
twenty students in class a and 20 students in class b were asked how many hours they took to prepare for an exam. the data sets represent their answers.

class a: {2, 5, 7, 6, 4, 3, 8, 7, 4, 5, 7, 6, 3, 5, 4, 2, 4, 6, 3, 5}
class b: {3, 7, 6, 4, 3, 2, 4, 5, 6, 7, 2, 2, 2, 3, 4, 5, 2, 2, 5, 6}

which statement is true for the data sets?

a.
the mean study time of students in class a is less than students in class b.
b.
the mean study time of students in class b is less than students in class a.
c.
the median study time of students in class b is greater than students in class a.
d.
the range of study time of students in class a is less than students in class b.
e.
the mean and median study time of students in class a and class b is equal.

Step-by-step explanation:

The mean of class A is

2+ 5+7+6+4+3+8+7+4+5+7+ 6+3+5+4+2+4+6+3+5)/20

= 96/20 = 4.8

The mean of class B is

3+7+6+4+3+2+4+5+6+7+2+2+2+3+4+5+2+2+5+6 = 80/20 = 4

Median for class A is 5

Median for class B is 4

Therefore, the following statements are true for

B. The mean study time of students in Class B is less than students in Class A.

i need the table so i can see

step-by-step explanation:

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
